IMPROVEMENT IN CAR-AxLEs.

Specification forming part of Letters Patent No. 148,705, dated March 17, 1874 g application tiled December 9, 1873.

' To all whom 'it may concern:

Illinois, have invented certain Improvements in Railroad Vheels and Axles, ot' which the following is a speciiication:

My invention relates to improvements in ear-axles; and consists in the employment ot'- two sleeves tting loosely over the car-axle, to which the wheels are attached, so that each wheel can move independently of the other in combination with collars fitting over the axle and working in oblong slots therein, as hereinafter more fully set forth.

In the accompanying drawings, A is the earaxle, and H H are two sleeves or hollow cylin ders iittin g over the axle, to which the wheels B B are attached, thus allowing the wheels to turn on the car-axle independently of each other, so that in turning a curve the inner Wheel may revolve slowly, thus avoiding in a great degree the friction of the inner wheel on the rail. The inner ends of the sleeves H H are terminated by disks or collars G G, one of which has a projection which lit-s into a corresponding recess in the other. I is a washer, situated between the collars Gr G. The wheels B B are made in the ordinary manner, except ing that a recess is cast in the outer side of each for the reception of flanged collars F F,

situated on the ends of the axle, the tlanges on the collars tting into the recesses inthe wheels. C is an oblong slot made in the end of the axle, akey, D, being inserted in a per foration in the collar, and passing through the oblong slot C in the axle. E E are screws, inserted into screw/threaded tubular recesses in the ends ot' the axle, and having their inner ends bearing against the keys D D. J are oilcups fastened to the sleeves H H.

I am aware that a divided tubular axle having the ear-wheels tixed thereto, and a solid undivided center-piece or mandrel, whereby the two parts of the said tubular axle are secured together so as to rotate independently of each other, have heretofore been employed; and I, therefore, lay no claim to such invention.

I claim as my inventionrlhe caraxle A, provided with oblong slots C C, in combination with the sleeves H H attached to the car-wheels B B, iianged collars F F, and keys D D, substantially as described, and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 19t-h day of November, A. D. 1873.
